RG1.92(2006版)为了考虑反应谱分析高频部分的质量丢失问题,将核电厂结构、系统和组件的地震响应分为2个部分:周期性反应和刚性反应。核电厂安全壳内的钢平台地震响应包括刚性反应和周期性反应,需要将刚性反应和周期性反应剥离开来分别计算。分别使用Gupta法+Missing Mass法和Lindley-Yow法+静态零周期加速度(ZPA)法,通过GTStrudl软件的程序语言编制满足这2种组合方法要求的计算程序,以一个钢平台为实例,对比研究2种谱分析方法在实际应用中的差异,确定核电厂安全壳内的钢平台分析设计采用的反应谱分析方法。
RG1.92 (2006 edition) In order to consider the mass loss of high-frequency part of response spectrum analysis, the seismic response of nuclear power plant structure, system and component is divided into two parts: periodic response and rigid response. The seismic response of the steel platform in the containment of nuclear power plant includes rigid reaction and periodic reaction. The rigid reaction and periodic reaction need to be peeled apart to calculate separately. The Gupta method + Missing Mass method and the Lindley-Yow method + ZPA method were used respectively to compose the calculation program to meet the requirements of the two combined methods by GTStrudl software programming language. Taking a steel platform as an example, comparative study 2 kinds of spectral analysis methods in practical application of the difference to determine the nuclear power plant containment within the steel platform analysis and design of response spectrum analysis method.
